:tisk: That's great that you have the option to delete and receive a credit. My suggestion is to get the factory XM system because it's available. You can always add the aftermarket Sirius system and have both if you choose. Later on you might decide you like XM better. There's nothing like the factory system.longislander said:Check out Cadillac.com...it's now possible to build your new CTS with XM delete, for a credit of $325. I'm going to go with a Sirius add-on (Howard Stern fan) so I'm glad this delete option is now available.
